Rubus plant named ‘JdeBoer19’

ABSTRACT

A new cultivar of  Rubus  plant named ‘JdeBoer19’ that is characterized by its fruit production on primocanes, its compact plant habit, its abundance of fruit with a sweet taste, and its canes with minimal thorns.

Botanical classification: Rubus idaeus.

Cultivar designation: ‘JdeBoer19’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Rubusidaeus named ‘JdeBoer19’ and will be referred to hereinafter by itscultivar name, ‘JdeBoer19’. ‘JdeBoer19’ represents a new cultivar ofraspberry plant grown for fruit production.

‘JdeBoer19’ was discovered by the Inventor as a chance seedling in 2010in the Inventor's garden in Boelenslaan, The Netherlands. The parentageis unknown.

Asexual propagation of the new cultivar was first accomplished by theInventor by stem cuttings in March of 2011 in Boelenslaan, TheNetherlands. Asexual propagation of the new cultivar by stem cuttingshas shown that the characteristics of the new cultivar are stable andreproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent thecharacteristics of the new cultivar. These attributes in combinationdistinguish ‘JdeBoer19’ as a new and unique cultivar of Rubus.

-   -   1. ‘JdeBoer19’ exhibits fruit production on primocanes.    -   2. ‘JdeBoer19’ exhibits a compact plant habit.    -   3. ‘JdeBoer19’ exhibits an abundance of fruit with a sweet        taste.    -   4. ‘JdeBoer19’ exhibits canes with minimal thorns.

‘JdeBoer19’ can also be to Rubus cultivars ‘Nr7’ (U.S. Plant Pat. No.22,141), ‘Boyne’ (not patented) and ‘Royalty’ (not patented). ‘Nr7’ issimilar to ‘JdeBoer19’ in having a compact plant habit. ‘Nr7’ differsfrom ‘JdeBoer19’ in producing fruit on floricanes. ‘Boyne’ is similar to‘JdeBoer19’ in producing an abundance of sweet fruit on primocanes butdiffers from ‘JdeBoer19’ in having less compact plant habit. ‘Royalty’is similar to ‘JdeBoer19’ in producing fruit on primocanes but differsfrom ‘JdeBoer19’ in having a less compact plant habit and in producingfruit that are purple-red in color.
